in principle the umd port is a fast in put into the psp with its own power supply.
the psp could there for be recoded to use the umd port for other purposes, such as with the previous touch screen project there was a secondary chip in that case a attiny84 to convert the touch screen signal to a sio signal for the sio port (which is slow and over complicated), if the umd port is used this is nolonger needed , because the touch screen could be hooked up directly to some of the ports and the power source. then the psp can do the conversion of the data to a compatible format.
the only programing needed is psp programing to hook the umd drive prot and the conversion of the data(much faster than the sio port and less complicated).
based on this principle other things are also possible for instance to attach a solid state hard drive, other storage devices, (this is a stretch) expanding the ram(it is fast enough), a better resolution camera, a second controller.
any thing that is purely input for the psp.
just ideas on the applications of the port since I removed my umd drive.
give any input on this.
I would like to know what you guys think and if I design some thing to use it if I will have programing support.
